Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584308, here are decompositions:

61 + 31584247 = 31584308
97 + 31584211 = 31584308
241 + 31584067 = 31584308
337 + 31583971 = 31584308
367 + 31583941 = 31584308
397 + 31583911 = 31584308
499 + 31583809 = 31584308
607 + 31583701 = 31584308

Showing the first eight; more decompositions exist.
